[PATCH AUTOSEL 5.4 28/30] mmc: f-sdh30: Add quirks for broken timeout clock capability

[Sasha Levin]

From: Kunihiko Hayashi <hayashi.kunihiko@xxxxxxxxxxxxx>

[ Upstream commit aae9d3a440736691b3c1cb09ae2c32c4f1ee2e67 ]

There is a case where the timeout clock is not supplied to the capability.
Add a quirk for that.
